Abstract: PURPOSE:To secure a sufficient breakdown strength difference from a light- receiving region by constituting a second compound semiconductor layer of a first layer having low impurity concentration, a second layer having high- impurity concentration and a third layer having low impurity concentration and forming a guard ring layer up to the depth passing through the third and second layers reaching near the interface of the first and second layers. CONSTITUTION:An n-InP layer 12 having low impurity concentration, an n-InP multiplication layer 4 having high-impurity concentration, further an n-InP layer 5 having low impurity concentration are formed on an n-InGaAsP intermediate layer 3. In the center of an n<->-InP layer 5, a p<+>-InP region 6 is formed, which is a light-receiving region due to diffusion of Cd so far as reaching near the interface of the n-InP layer 5 and the n-InP multiplication layer 4. A guard ring 7, in which Be formed around the p<+>-InP region 6 is ion-implanted, is deeply formed passing through the n-InP layer 5 and the n-InP multiplication layer 4 so far as reaching near the interface of the n-InP multiplication layer 4 and an n-InP layer 12. Thereby, the guard ring has breakdown strength sufficient even when the concentration of the n-InP multiplication layer 4 is raised can be secured.

Abstract: PURPOSE:To confirm an erasing program en bloc and to shorten the erasing time by providing a differential amplifier array for comparing the potential of each bit line with a reference voltage, applying a voltage higher than the threshold voltage at the time of writing on a word line and applying a prescribed voltage on a source line. CONSTITUTION:A bit line selection circuit 3 is made into a non-selection state, circuits 5-8, 10 are caused to perform a prescribed operation by means of a signal phi-... and, first, a source line S is made to be (0)V potential. Consequently, the bit lines B1-... discharge the electric charge of a memory cell transistor(Tr) 1, become a (0)V potential and the (0)V potential of the lines B1-... and a reference voltage 3V are inputted to a differential amplifier array 7. In such a condition, when the lines B1-... are separated from a line S by means of a signal phip and the voltage of the line S is made to be 5V, When the voltage of the lines B1-... exceeds 8V-5V=3V, the array 7 outputs a H level and a decision circuit 10 outputs an error signal ERR. Consequently, the confirmation of an erasing program en bloc of the transistor Tr1 whose threshold voltage is not higher than 5V is executed and the erasing time is shortened.

IPC: H03K19/0175
Filed: 1986-12-17
Abstract: PURPOSE:To accurately set the drain current of a high voltage N-channel double diffusion transistor, by impressing a low voltage power source on the gate of a low voltage P-channel MOS transistor on a prescribed condition. CONSTITUTION:The gate 12 of the low voltage P-channel MOS transistor (TR)6 is connected to a CMOS logic part, and a low voltage high potential power source voltage or a ground potential is impressed on it on the prescribed condi tion. Since the TR6 is structured in MOS structure not in double diffusion, it is possible to easily vary an ON-resistance to a ratio of channel length and channel width. A current decided mainly by the ON-resistance of the TR6 is permitted to flow on the high voltage N-channel double diffusion TR7 whose gate and drain are short-circuited, and the gate and the drain voltage of the high voltage N-channel double diffusion TR8 are generated. The ratio of the channel length and the channel width of the TR6 decides the drain currents of the TRs 7 and 8 mainly, however, since it is possible to set the ratio of the channel length and the channel width with high accuracy, it is possible also to set the drain current of the TR8 with high accuracy.
